LOCK.

SPECIFICATION forming part of Letters Patent No. 342,611, dated May 25,1886.

Application filed March 11, 1886.

To all whom it may concern.-

Be it known that I, SEPASTIAN LANDGRAF, a citizen of the United States,residing at New York, in the county and State of New York, have inventednew and useful Improvements in Looks for Boxes, 850., of which thefollowing is a specification.

My invention relates to improvements in looks, such as are especiallyadapted for use on boxes, coffins, and the like; and it consists,essentially, in the c0mbination,with a lockplate and catch-plate, ot' arecessed catch on the catch-plate, asliding bolt adapted to engage thecatch when in its locking position, guides for the sliding ,holt, a stemprovided with a Web which engages the sliding bolt, and a tumbler-springfor locking the bolt in its locking and unlocking positions, all ofwhich is more fully pointed out in the following specification andclaims, and illustrated in the accompanying drawings, in which Figure lis a sectional plan view of my improved lock, showing the sliding boltin its unlocking position. Fig. 2 is a similar view thereof,representing the sliding bolt in its locking position. Fig. 3 is a sideelevation of Fig. 2. Fig. 4 isa sectional view on a smaller scale thanthe preceding figures of my look as applied to a coffin. Fig. 5 is asection in the plane 00 00, Fig. 1.

Similar letters indicate corresponding parts.

In the drawings, theletter A designates the catch-plate, and B is thelock-plate, the two portions of which latter form a right angle witheach other.

From the catch-plate A projects a catch, 0, which is provided with arecess, 0, and extends through a suitable aperture in the lockplate whenthe lid or cover is closed, and the recess therein is thus brought intoa position to be engaged by a sliding bolt, D, when the latter is throwninto its locking position. This bolt D is constructed with a guideway,d, which engages witha guide-pin, d, that is secured in or formedintegral with the lockplate, and it is thrown into its locking andunlocking positions by suitable means. In the example shown in thedrawings the bolt is provided with anotch, e, that is engaged by a web,6, extending from a stem, E, which is pivoted in the lock-plate. Thestem is provided with a square or hexagonal head, and is turned tooperate the bolt by means of a key, E, Fig. 1, properly constructed forthat purpose.

Serial No. 194,873. (No model.)

To look the bolt in its locking and unlocking positions, I make use of atumbler-spring,

engages a post, f, with its free end, which free end is provided With anupwardly-inclined working-lace, 1, and a second working-face, 2, thatforms an angle with workingface 1. \Vhen the bolt is in its lockingposition, Fig. 2, the face 2 engages the postf and locks itin thisposition, and when the bolt is in its unlocking position, Fig. 1, theface 1 engages the postf and retains the bolt in this position.

A look constructed according to'rny invention is available for allordinary purposes, and it can be applied also to the body of a coffinwithout interfering or obstructing the groove 9, in which is retainedone edge of the covering-glass G, whereby the lock is renderedexceedingly valuable for this purpose.

What I claim as new, and desire to secure by Letters Patent, is

1. The combination of the plate A, having the catch 0, provided with therecess a, with the right-angled lock-plate B, having the stationarypin], the guided bolt D, sliding horizontally under and parallel withthe top flange of the lock-plate to engage the recessed catch, and thespring F, attached at one end to and sliding with the bolt, andextending longitudinally from the latter and provided with the twoworking-faces l and 2, located at an angle to each other, for retainingthe bolt in its locking and unlocking positions, substantially asdescribed.

2. The combination, with thelock and catchplates constructed asdescribed, of the catch 0, the recess 0 therein, the sliding bolt D,constructed to engage the recessin the catch, the slot (1 therein, andthe pin 01, for guiding the bolt, the notch e in the bolt, the stem E,and web 6 thereof, for operating the bolt, the postf, the tumbler-springF, having two inclined working-surfaces, 1 and 2, constructed to engagewith the post, substantially as shown and described.

In testimony whereof I have hereunto set my hand and seal in thepresence of two subscribing witnesses.
